Exquisite air sac histological traces in a hyperpneumatized nanoid sauropod dinosaur from South America
Abstract This study reports the occurrence of pneumosteum (osteohistological structure related to an avian-like air sac system) in a nanoid (5.7-m-long) saltasaurid titanosaur from Upper Cretaceous Brazil. We corroborate the hypothesis of the presence of an air sac system in titanosaurians based upo...
